Cara has to meanings
cara is a noun, caro/a is an adjective
Is cara feminine because of casa or doctora?
Casa since the house is expensive, not the doctor
I find that the male voice sometimes does not pronounce words clearly, I cannot hear the a on the end of cara.
In previous lessons, "medico" was translated as "doctor". What's the difference between medica and doctora.
Same in my understanding.
